FNEUMAIC SANDER.

Application filed July 3,

My invention relates to pneumatic sanders, and has for its object to provide a new and efficient sander for locomotives.

A further object is to provide a sander for locomotives where air is the power used to blow the sand from the sand box to the rails on which the locomotive runs.

A still further object is to provide a pneumatic sander for lrailroad, street cars or other vehicles which run on rails which will elliciently blow the sand upon the rails on which they run and will not clog or jam, and which is easily cleaned when dirt or scale has collected therein.

These objects l accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specilication forming a part of this application and pointed out in the appended claims.

ln the drawings in which I have shown the best and most preferred manner of building my invention, Figure l is a view of my device in place in the sand box of a locomotive. Figure 2 is a longitudinal vertical section on line 2 2 of Figure a. Figure 3 is a longitudinal horizontal section of the device on line 3-3 of Figure t. And Figure l is a front elevation.

In the drawings l have shown the sand box or sand dome of a locomotive as A, within which box my sander is mounted. The sander consists of a cast-ing B, having an integral flange l formed on one end thereof, and with the other end portion of said casting formed into a Ushaped pipe 2, with the interior or bore a of the said pipe extended through the said Acasting B and flange portion l. A tapered member 3 is integrally formed between the legs of said U-shaped pipe. and having` a longitudinal central hole 9 therein, which is in open connection with the interior bore 4 of said pipe 2. The said hole 9 is enlarged in the tapered end at 8 to allow a free passage for the air passing therethrough, and the end of the hole 9 which extended through the pipe 2 is internally threaded to receive a plug 12, for closing that end. A centrally disposed hole 5 is formed in the casting B and is internally threaded at one end thereof to receive the sand pipe 6, which carries the sand to the rails. The ends of the said bore e in the casting B are internally threaded and the 192e. Serial No. 120,349.

upper end receives the pipe 10 which carries he air supply to the sand box, and the other end receives the clean-out plug l1. The said plug ll may be removed when necessary and with the force of the air in the pipe 10 passing through the bore l, the lower portion of said bore will be thoroughly cleaned out and the plug ll may then be. replaced. rlhe said flanged portion l and the main casting B are at an angle to each other so that when the device is in place in a sand box the flanged portion l is parallel with the side of the box and the casting B is at an incline to the side wall of the said box, which makes the bore l easier to clean out and the action of the sand on the air more positive and quicker than when the castingv is level with the bottom of the sand box.

The operation of my invention is as follows:

llVith the casting B secured inside the sand box or dome of the locomotive, and the flange l outside said deine to hold the casting in place, and the supply pipe l0 and the sand pipe 6 in place, the device is ready for operation. llVhen it is necessary to stop the moving locomotive sand may be applied to the rails to make the friction greater and thus make a quicker stop. When the sand is necessary, air is introduced through the pipe l0 and said air will pass through the bore 4i, the holes 9 and 8 and carry sand through the hole 5 into the pipe 6 and down to the rails in any desired amount.

Having thus described my invention, I desire to secure by Letters Patent and claim zl. In a sander for locomotives, the combination of a casting having an integral flange formed on one end thereof and at an angle to the main casting; a 't5-shaped portion integral with said casting and internally bored; a tapered member integral with said U-shaped portion and parallel with the arms of said U-shaped portion and having an internal bore constricted at its large end; a central bore in said casting parallel with the arms of said U-shaped portion; and a delivery pipe secured in said central bore.

2. ln a pneumatic sander of the class described, the combination of a casting; an integral flange on one end thereof and at an angle thereto; a U-shaped casting integral with said casting on the other end; a central bore through said U-shaped casting and the main casting; a supply pipe secured in the upper end of said bore and a plug secured in the lower end of said bore; a tapered member parallel with the legs of said U- shaped casting having a central bore therein With one end constrieted; a larger central bore-through said casting parallel with the In testimony whereof I have affixed my s1gnature.
